#define MPLONG INTEGER(kind=8)
C The total number of bits in an MPLONG
#define WORDLEN 64
C The number of bits in each digit word used by the multiple
C precision structure (normally WORDLEN/2).
#define BITSPERWORD 32
C The number of usable bits in the mantissa of a double
C (Look in the file /usr/include/float.h)
C Also define a fudge factor so that for any values of rem and div:
C floor(rem/div) > int(float(rem-DIVFUDGE*2^stuff)/float(div))
C where float(x) is the double precision representation
C of the top DBL_MANT_DIG-1 bits of x and stuff is chosen so
C DIVFUDGE effects only the bottom bits of those chosen by float.
C
#define DBL_MANT_DIG 53
#define DIVFUDGE 3
C There are 64 bits in an INTEGER on the T3E. This is important
C because many functions in MPUTIL return an INTEGER, not an MPLONG.
C
#define INTEGER_BITS 64
#define VECTLEN 1
C Define a string containing a single backslash
#define BACKSLASH "\\"
